Good news for those loyal to the SRAM Red eTap group but were less than thrilled with the previous range limitations. Today SRAM announced a new Red rear derailleur, compatible with a 10-36t cassette, similar to the previous Force eTap upgrade. There are two models of derailleur now, a 33t-max and a 36t-max.
